Rishabh Maurya commented on OAK-2774:
-------------------------------------
Added following test case at LuceneIndexTest.java and it fails -
{code}
@Test
public void testLuceneQueryParserEscape() throws Exception {
NodeBuilder nb =
newLuceneIndexDefinition(builder.child(INDEX_DEFINITIONS_NAME), "lucene",
of(TYPENAME_STRING));
TestUtil.useV2(nb);
NodeState before = builder.getNodeState();
builder.child("a").setProperty("foo", "/bar");
NodeState after = builder.getNodeState();
NodeState indexed = HOOK.processCommit(before, after, CommitInfo.EMPTY);
IndexTracker tracker = new IndexTracker();
tracker.update(indexed);
AdvancedQueryIndex queryIndex = new LucenePropertyIndex(tracker);
FilterImpl filter = createFilter(NT_BASE);
filter.setFullTextConstraint(new FullTextTerm(null, "/bar", false,
true, null));
List<IndexPlan> plans = queryIndex.getPlans(filter, null, indexed);
Cursor cursor = queryIndex.query(plans.get(0), indexed);
assertTrue(cursor.hasNext());
assertEquals("/a", cursor.next().getPath());
}
{code}
